We're going to be giving away five codes for Armored Core Last Raven Portable this Thursday on Kotaku's Facebook.

Armored Core Last Raven Portable is the latest Armored Core port to make its way from the Playstation 2 to the Playstation Portable. The PSP version of the third-person mech shooter includes Ad Hoc mulitplayer for up to four players, more than 500 mecha parts to build your own Armored Core with, new opponents, a branching story with multiple endings.

Last Raven Portable will also accept game saves from Armored Core 3 Portable and Armored Core Silent Line Portable.

Head on over to our Facebook page tomorrow for a chance to win one of the copies. I'll be dropping the codes in there for folks to grab and use. So you may want to bring your PSP with you to work, school or, I don't know, the beach tomorrow to make sure you can use the code before someone else does.
